Murder is just around the corner... The Connection Investigation Agency is under new management, with partners Tessa, Luke, and Beth at the helm. As they reopen the office, a chilling discovery is made - a body hidden in the outhouse, bones lying undiscovered for twenty-five years. While Luke faces his first solo case, Tessa, a former DI, must prove herself, unravelling the mystery behind threatening notes sent to two women who later become murder victims.
